Prerequisite links organize information in a progressive manner, moving from broader concepts to more specific details. This format is advantageous in an educational context because it enables users to grasp the fundamental knowledge entities that inform or provide necessary information to understand other entities. For example, if a user encounters a knowledge entity they find difficult to comprehend, prerequisite links would connect it to other entities that the user needs to grasp first. This approach facilitates a step-by-step acquisition of knowledge, building on previously learned concepts, and enhancing a more thorough understanding of the topic.
